Subject: [PATCH 12/12] btrfs: stop using the btrfs_bio saved iter in index_rbio_pages
Date: Mon,  4 Apr 2022 06:45:28 +0200	[thread overview]
Message-ID: <20220404044528.71167-13-hch@lst.de> (raw)
In-Reply-To: <20220404044528.71167-1-hch@lst.de>

The bios added to ->bio_list are the original bios fed into
btrfs_map_bio, which are never advanced.  Just use the iter in the
bio itself.
